To all whom t may concern:

Be it known that I, HANS SoriMiDT, a subject of the German Republic, and resident of Oejendorf, bei Hamburg, Germany, have invented certain new and useful Improvements in lVindows y for'which patents have been obtained in Germany, No. 299,999, dated April 29, 1914; No. 306,669, dated December 24, 1914, and No. 323,694, dated February 27, 1919; in France, No. 518,630, dated June `28, 1919;,in Belgium, No. 232,519,

dated September 30, 1919; and an application filed in Holland April 22, 1920), of which the following is a specification.l y

This invention relates to a window coinprising two sashes arranged to lie in the same plane when closed, the topsash being guided bypins movabler infgrooves in the windowy frames, whilst the bottoni sash is adapted to swing with respect to the frame. The bottom sash is mounted on swinging arms hinged to the window frame, by means of which arms it can be swung on its horizontal axis, whilst the top sash is adapted to slide "in the window frame, and is drawn downward when ythe bottom sash is tilted, and can then also be tilted about a horizontal axis. In this way the outsides of the two sashes of the window are turned inward, so that they can be easily cleaned from inside the room.

The subject of the invention is illustrated in the accompanying drawing, which shows two preferred forms of the invention.

Figures 1 and 2 are vertical sections of the first form of the window with closed and opened sashes respectively shown; Fig. 3 is a vertical section of a modified forni showing the upper sash open; Fig. 4 is a vertical section of the form shown in Fig. 3 with the parts in closed position; Fig. 5 is section on line 5 5 Fig. 4.

The window consists of the top sash b and the bottom sash c which are mounted in the frame a. The top sash is guided between the grooves d of the window frame by means of pins e and f. The bottom sash is connected to the top sash by means of' a hinge g at the butt joint, and is pivotally connected by pins Z to rods 7L which are hinged to the window frame at z'. The window frame is provided with a groove 7c in which a corresponding fillet c of the sash fits in order to make a tight joint.

When the top sash b is pulled down, the bottom sash c describes a tilting movement about the pins Z. If the bottoni sash bev the guide pins passing out through gaps (Zin the window frame. f,

.the ijn-odii'ied forni shown in Figs. 3 to 'ithe top sash yo ris connected to bottoni sash c by means of a link lml on each side of the` sash.kv The upper end of each link is pivotally connected by a pin m to the top sash above the lower rail andthe lower end of each link is formed with an angular projection or yarm m? which isjpivotally connected to the lower sash by a pin m3. Guide `pins mf* on the links `project into Jthe longitudinal groves Z formed in the frame. A twoarm lever n is arranged on the window frame, and lits longer arm ,carries a pin n, which isbent at a right angle and adapted tobe received behind an arm oattachedtothe top sash Z). .A rod p operated by a handle n, is pivoted .on the short arm of the lever n? .,jf f, z

The window can be .locked by turn buttons s (Fig. 5) ofknown construction pro vided on the bottom sash well as on the top one.

rllhis form of window has the advantage that the top sash can be kept open while the lower sash is closed. To open the top sash, the turn buttons are rotated to release both sash. rlhe handle of the lever fr is pressed upward causing the 'free end of lever n to press against the upper sash. Simultaneously .with the pressure on the lever, the lower end of the bottom sash is manually pushed out and when the upper and lower sash (matched rails) become separated the upper sash is opened and the lower sash can be again closed. To close the upper sash when the lower sash is closed the latter must first be pushed out; the handle of lever r is then depressed causing the pin nto engage the arm o and swing the upper sash inward into the position shown in Fig. 4, the lower sash is then pulled in and locked by the turn-buttons s.

What i claim is:

1. rl`he combination with a window traine having grooves of two sashes arranged to lie in the saine plane and pivotally connected together, pins near the upper end of the upper sash arranged to slide in said grooves from the top to the bottoni thereof, and a suspending rod pivis Jfully closed.

3. The combina-tion with a window frame having an upper and a lower sash, pivotally connected together oil means to permitthe lower'sash to 'swing outwardly while the upper sash slides to the bottom of said frame, and means for holdingthe upper sash outwardly inclined while the lower sash is fully closed. l,

el. The combination -o-t a`window frame, an upper sash adapted to slide in the plane or' the 'frame from the top to the bottom thereof, a lower sash, means for flexibly Connecting vthe sashes together, means whereby the lower end of the upper sash maybe swung free of the frame, and means whereby the normal positionr of the loweisash may be substantially reversed.

A5. The Combination 'of a window trame,

two sashes adapted to lie therein in the same plane, means flexibly connecting the sashes together the top sash adapted to slide in the plane oitl the frame from the top to the formed in the frame whereby the lower end of the upper sash may be swung free of the frame, and supports pivoted near the top of the frame and Adirectly pivoted to the lower sash adapted to permit the normal position ofthe 'latter 'to be substantially reversed. y n I 6. The combination with a window frame having an upper and a lower sash hinged together, and means lfor inovably suspending the jlowersa'sh Vfrom the` frame, of means to permit the upper sashfto move to thebttom of said ytrame when'the lower sash is pushed outwardly and means to permit the lower end of the upper `sash to also swing outwardly and to holdtlie lower sash outwardly swung. '7. The combination with al window trame having an lupper and 'a lower vsash hinged together, vand means for movably suspending the lower sash from said frame, o'tmeans to permit the upper sashy to rvmove to the bottom of said frame when'the lower sash is ypushed outwardlyand'means to permit the lower end of the uppersash to also swing outwardly Ito hold the lower ysash outwardly swung, and mechanism to prevent 4at will the Complete lowering lof the upper sash and tohold it outx'vardly swung while the lower vsash is fully Closed.
